Good morning, afternoon, or evening everbody this story has been requested by KingJake53421. And under the royal highness himself I shall read the disclaimer: Touhou Project is owned by ZUN. So with that being said let's go, also MERRY CHRISTMAS OR HAPPY HOLIDAYS!

(Y/n) POV
It was a peaceful day in the Scarlet Devil Mansion without all the snow being here and causing a lot more work to be done around here. I was busy attending Flandre's room in order to get it all set up for Christmas. I heard the door to the basement open, and heard a familiar adorable voice.
???: Onii-chan! 'She quickly grabbed me and nearly crushed my back, until I felt her get off me instantly I looked behind to see my co-worker Sakuya Izayoi the elegant and beautiful maid of the Scarlet Devil Mansion.
Sakuya: Flandre I wish you would control your own strength remember you're a vampire and both (Y/n) and I are human. (Y/n) are you all right?
(Y/n): Yeah ow never better, and how are you doing Flandre-sama.
Flandre: I'm doing great Onii-chan. Onee-sama is being stubborn because she doesn't want to have fun, and play with me.
(Y/n): That's because young mistress your level of playing is too rough, and not at all gentle and calm. Luckily for you I found a solution to control that power of yours.
Sakuya: ! You have
Flandre: Really Onii-chan!
(Y/n): Yes I have, it took me a while to look it up in Patchouli's book, and practice it perfectly. So ready Flandre with this the power will be contained and you get to finally go outside and play.
Flandre: I'm ready Onii-chan! She eagerly jumped up and down waiting for the spell to begin.
Sakuya: This won't hurt imouto-sama will it? If so I will have to take care of it.
(Y/n): It won't hurt her, she'll feel a bit sleepy but that's about it, and about 6 hours from now that extra power will be sealed. So ready Flandre?
Flandre: Hurry Onii-chan.
(Y/n): All right after this you'll feel sleepy but that's the spell taking effect okay.
Flandre: Okay! 'As soon as she said that I began to build magic around me, and the sealing circle appeared underneath my feet I began to chant the words that I memorized and finally placed two of my fingers on Flan's forehead. After that the spell stopped.
(Y/n): It is done.
Flandre: *yawn* I feel sleepy, Onii-chan can you sleep with me?
(Y/n): (If I was in the outside world, and the cops heard that, I would already hear the sirens!) Oh....uh...Sakuya-san some help please?
Sakuya: No. It's best to attend the little mistress to her needs now than have her throw a tantrum I will get everything else ready okay. 'With that she gave me a wink and dissapeared.
(Y/n): *blush* (Wow she's so so beautiful and thoughtful.) Okay Flan time to go to bed okay.
Flandre: Y...a......y......zzzzzz. 'I saw that she was going to fall over so I caught her and placed her on her bed and I laid beside her.
(Y/n): Good night Flan. I took the blankets and covered ourselves up and began to sleep.
------6 hours later.
I woke up feeling some kind of weight clinging my arm and saw it was Flan she was hugging as tightly as she could but this time it didn't hurt the spell worked. She was clinging onto me tightly, but the extra power is sealed, looks like it also took care of that extra strength as well. I decided to wake up Flandre.
(Y/n): Flan- chan wake up. 'I gently nudged her in order for her to wake up.'
Flandre: Mmn just five more minutes Onii-chan. 'She kept using my arm as a hug pillow, but with her strength sealed it didn't hurt, and thank goodness for that. It was also cute how she was lightly snoring while a bit of saliva was coming out of the small opening of her mouth.
(Y/n): No Flan-chan time to wake up the spell worked, besides it's time to say hello to Onee-sama.
Flandre: Mmnn...okay. I saw her slowly get up and rub her eyes, and yawned a bit.
(Y/n): Time to put on some new clothes and then meet Onee-sama okay Flan.
Flandre: Okay Onii-chan.

----------Remilia's POV
I was in the throne room, waiting for my tea to arrive I can't help but laugh a little on how this whole process came to be. I never thought having a human live here and be Flandre's servant would make Flan become a lot more cheerful and happy. I was glad I made that choice, however there was a small complication I didn't foresee and that would be that my mansion.....is now fully decorated top to bottom with all sorts of lights, and ornaments it did brighten up the mansion to my dismay but who says that the Scarlet Devil Manaion can't be in the Christmas mood. As I was thinking of how all this came to be, Meiling came in with a tree, and behind her I saw (Y/n) and my little sister Flandre wearing a santa outfit, helping Meiling out.
Meiling: Okay place it here!
(Y/n): Right!
Flandre: Okay.
They placed the tree beside the door, and I saw Meiling carrying a bag.
Remilia: Meiling are those Christmas ornaments?
Meiling: Yep we were just about to decorate the tree.
(Y/n): Remilia-sama I bring you good news. Flandre go ahead and show her.
Flandre: Okay. She then began to fly over to her, and stood still.
Remilia: Hmm.....'I looked at my sister and sensed that her strength has been severed in half no more like sealed. Half of her power was sealed. Flandre why is your strength halved?
Flandre: Onii-chan found a spell to help control the excess power. Thank you Onii-chan.
Meiling: Seriously wow, that's some impressive work good job (Y/n).
Sakuya: I'm quite impressed as well. You managed to seal off half her power.
(Y/n): Thanks but I couldn't do this without Patchouli-sama's help so thank her for teaching me how to perfect it. Flandre ready to go outside and play?
Remilia: WHAT?!
(Y/n): Remilia-sama it's okay, she won't leave. 'We'll just be in the garden outside, also everyone I got you your Christmas outfits thank you Sakuya for giving me the measurements. (Although never expected Sakuya, and Meiling's cup size to be equal. That's a shock!)' Here you all go so Flandre ready since you're all dressed let's go outside and play.
Flandre: Okay Onii-chan. 'I saw (Y/n) leave with Flandre it was somewhat cute seeing those two together it's like those two are the siblings. I looked at my outfit and saw that it looked nice and everyone else except Sakuya was beginning to put their's on. I wonder what outfit did he make for Patchy....
------Meanwhile at Grand Voile
Patchouli was wearing a red Santa outfit along with a Santa hat that has her crescent moon shaped accessory , as for Koakuma she is wearing a Santa outfit that shows off the curves, but conceals a lot on the body.
Koakuma: This is amazing Patchouli-sama, I never knew that (Y/n) was really good at sewing.
Patchouli: He did practice with Alice on sewing, and from me he practiced that spell to seal half of Flandre's power. So everything turned out great. Now if you'll excuse me I'll be back to my book.
-------Back to (Y/n) and Flandre.
(Y/n): Okay Flan ready!
Flandre: Mmhm! 'I opened the doors and Flandre took her first steps outside.' Wow it's so beautiful!
(Y/n): Okay Flan don't go beyond the gate for now you can play around here.
Meiling: Wait for me please! 'I turned to see Meiling and my god did she look hot! I don't know what I was on when making the outfit but somehow it leaves a lot of eye candy. The outfit showed off her curves a lot, and the stockings made the appearance a lot more alluring.
(Y/n): (Focus no time to drool!, although.....dammit focus!) 'I turned my attention away from Meiling , in order to focus on Flan, the weather was surprisingly mild despite it being winter.' What is it Meiling-san?
Meiling: I was actually asked to oversee you and Flandre-sama's playtime until Sakuya-san calls for me.
(Y/n): Don't worry we'll be right where you can see us. Flan want to play a game that is perfect during winter, but first wear this. 'I gave her mittens that way she can hold the snow.'
Flandre: Mittens?
(Y/n): Yeah now wear the mittens and grab some snow.
Flandre: Okay! 'She began to gather snow in her hand, and made a fist making the snow come out of her hand.'
(Y/n): Flan no, you're supposed to hold it like this. 'I grabbed some snow and began to form it into a ball.
Flandre: I see and then?
(Y/n): You throw it! Here throw the snowball at me.
Flandre: Okay! She took the snowball from my hand and threw it at me, and thank goodness half her power was sealed if not I don't know what might happen, but it might mean a trip to Eirin's clinic.
Meiling: Are you okay?
(Y/n): I'm fine remember her strength is halved! Want to join in on the fun
Meiling: Oh right, and no thanks, maybe later.
(Y/n): All right then. Flan let's make a fort that way you can protect yourself from the snowballs in which I will be throwing.
Flandre: Why?
(Y/n): It's a snowball fight silly. So get ready!
Flandre: Okay Onii-chan! She began to make her fort while I made mine, but her fort kept falling so I helped her out until both of ours was done.
(Y/n): Okay ready for the fight to begin!
Flandre: Yeah! Let's go!
---------Sakuya's POV
I was getting my mistress' tea ready, until I saw something from the corner of my eye when I looked out that window. I saw that (Y/n)-san, and Imouto-sama were busy building a fort, getting ready for a snowball fight. Lately Imouto-sama has been feeling down lately and she mostly stays here in the basement, but when my mistress offered an outsider shelter here. I thought he wouldn't last being the imouto's servant but he actually did far better than any of us could to cheer imouto-sama up. He made her laugh, played games with her, and helped her learn. He even taught her how to cook. At first I was against the idea, but after trying to convince me a lot of times I allowed it soon enough those two became really close like siblings. When Marisa-san comes in here to "borrow" books, he helps me out in getting her out of the premises quite easily. He can also be quite the entertainer for imouto-sama, he makes her feel happy, and over time I became a bit jealous of her because I would like it if he did that sort of thing with me. He shows compassion, is very nice, and helpful, and knows how to make people smile. It really amazes me on how a person like him exists in the outside world and not here. But over time I haven't been seeing him as a co-worker anymore, I saw him as someone who I want in my life, I wanted him, but with my mistress I can't abandon my duties to her. It would be nice if I could spend some time with him. The mistress tea is finished, and I instantly brought it to her.
Remilia: Sakuya are you feeling all right?
Sakuya: Yes I feel fine why do you ask?
Remilia: Lately I've been noticing that you tend to gaze into space with a bit of red on your cheeks.
Sakuya: Mistress I'm sorry I've been slacking on my duties I promise to never let it happen again.
Remilia: Just tell me what is on your mind? If you tell me then I could help you out, after all you are my best servant and  a great friend to me.
Sakuya: Lately I've been having feelings for someone, and it's just that I can't abandon my duties to you. I'm so confused as to what to do.
Remilia: I see....so go right ahead and let out your feelings to "him". After all he is the one who can brigthen anyone's day, and who wouldn't want a guy to make them feel happy. My guess Flandre knows what to give him as a gift, and everyone else as well. But my question to you is what will you give him?
Sakuya: I don't know....'I looked and saw my Santa outfit. (Wait I think I know what to do!) But mistress I can't just aband-
Remilia: Sakuya enough as an order, I order you to be yourself, pretend like I'm not here for an entire week I'll manage on my own.
Sakuya: But mistress I
Remilia: Enough! You've been working for me for a long time, and you deserve a break, as well as a shot to discover your emotions. So please do this not for my sake but for yours and your well-being okay. Now bring those two back it's time for the party and gift exchange to begin.
Sakuya: I understand thank you mistress. 'I went to Meiling and saw that those two were fighting and laughing at the same time.' I'll get the towels ready.
Meiling: No need I already got them. He really is something you know, good luck on confessing to him.
Sakuya:*blush* T-T-Thank you Meiling-san.
Meiling: Okay you two time to come back, it's time for the party to begin!
(Y/n): Okay Flan let's go!
Flandre: Okay Onii-chan, but I want to give you a gift first.
(Y/n): A gift sure but what is it?
Flandre: Come closer. 'I went down a bit more closer only Flandre to bite me on the neck.
Meiling & Sakuya: (Y/n)!
(Y/n): Ow! Flandre that hurts! Oh boy I'm feeling a bit woozy. 'I felt someone catch me.
Meiling: Flandre-sama why did you bite him?
Flandre: Because I want him to stay by my side forever. He makes everyone happy, and I don't want him to die early as a human.
Meiling: But did you take his feelings into account?
Flandre: No...'She looks at the ground almost beginning to cry.'
(Y/n): Ngh huff...huff..don't cry Flan-chan.
Flandre: Onii-chan I'm sorry! 'I felt her start to cry and I hugged her.
(Y/n): Flan it's okay, I'm not mad. Besides this was your gift to me wasn't it, then I'll make sure I'll use your gift right somehow okay. So turn that crying face into a smiling face okay.
Flandre: Sniff....okay. She let out a little smile as I wiped her tears, now come on let's go back to the party. I carried Flan on my back in order to make her happy, but Meiling stopped me.
Meiling: Wait before you do anything here take a look. 'She held a mirror in front of me and I saw my eyes turn from (e/c) to scarlet red. Are you sure you're feeling okay?
(Y/n): I told ya Meiling-san I'm fine. Now let's get going although the eye color changes back to normal right.
Sakuya: Yes it does, so don't worry, and now Flandre has officially marked you as her servant.
(Y/n): I don't mind so long as she's happy. Right Flan?
Flandre: Mmhm!
Sakuya: (Now things maybe a bit complicated, since she marked (Y/n) as hers, and I hope I can get through this without her throwing a tantrum. I'll speak to her later. What's even more amusing to me is that he's taking it in stride, without a care in the world not knowing his lifespan has increased along with his appearance he could be 90 years old and still look like he's in his 18's, along with the strength of a vampire at his side.) I'll get everything ready then.
(Y/n): Okay. 'I saw Sakuya vanish and I was carrying Flandre, and Meiling was walking beside me all the way to the dining hall where food was distributed, and everyone was wearing their Santa outfits except Sakuya which is understandable since she serves Remilia.' Okay time to eat!

Everyone: Yeah!
We all sat down to eat, and I saw that Sakuya was looking between Flandre and me worriedly, until Remilia told Flan to leave me alone for awhile, and that she will play with her. I don't know what that's about but whatever makes her happy. As dinner and gift giving was done, I helped Sakuya wash the dishes and she told me to wait in my room in which I agreed to after that was done, she vanished while I went to my room. When I arrived there I was not expecting the sight I was seeing.
(Y/n): (Damn! Now this is a side of her I never anticipated, but wow!)

Sakuya: Do you like it? I hope you enjoy your gift (Y/n). Also I want to say something throughout the times we've been together, I'm glad that I knew you and I wanted you to know that I l-l-l-love you (Y/n)! She gives me a look that shows her blushing along with something else on the lines of love and lust.
(Y/n): Yeah me too Sakuya-san I love you as well, and wow I've never seen this side of you but you look very beautiful, and wow...I'm speechless.
Sakuya: So want to unwrap your present. She held her arms out ready to embrace me.
(Y/n): Yeah I'm ready.
----Next morning.
(Y/n): (Wow that felt amazing! I never felt anything like it....it felt wonderful.) 'Next to me I felt Sakuya waking up.' Good morning Sakuya-chan did you sleep well?
Sakuya: Yes I did, and I really enjoyed my gift yesterday. 'As she said that with a tint of red in her cheeks. However as she tried to stand up she had a bit of trouble.' We've been doing it since last night, and it seems that I can't walk or stand properly. You really are something else (Y/n). I love you.
(Y/n): Yeah I love you too. (Hopefully Remilia doesn't kill me for putting her maid out of commission for awhile.)
Sakuya: So we have the entire week to spend for ourselves so what do you want to do?
(Y/n): (So I'm safe thank goodness.) Well how about I become your servant Milady? 'I said cheekily. It was cute seeing her face turn red.
Sakuya: *blushes* I-I-I-It's not necessary.
(Y/n): I'll get the food ready. 'I left the room to go to the kitchen.' (This feels like one heck of a dream come true, and I know that later on we'll get to experience lots of new things so long as we have each other, and our masters. I got her breakfast and tea ready and went back to the room.
